Singer-songwriter Imogen Heap isn’t your usual coffeehouse act. The Grammy-nominated British performer specializes in heavily produced, ornately arranged pop that features elements of electro, rock, and dance. Last year’s Ellipse features many of the distinctive indie-pop stylings that made her 2005 breakout album, Speak For Yourself, such a hit, while incorporating international touches gleaned from her round-the-world writing trip. But, staying true to the independent artist’s DIY ambitions, Heap completed the album in a studio converted from the playroom in her parents’ house. The result is an intricately layered record that’s both far-flung and invitingly intimate. She draws listeners in even closer on her latest release, a late-2009 iTunes-exclusive live EP documenting a London stop on her 2007 iMegaphone tour, where Heap's songs are stripped to bare, piano-and-vocals-only renditions.
